What Has ROE Got To Do With Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company’s earnings growth potential. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio.
